Bug ID: 413700
Summary: Plasma crash when hitting Ctrl+Z
Product: plasmashell
Version: 5.17.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: broekhoff.joc...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.17.2)
Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.3.7-arch1-1-ARCH x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Running Chrome, Dolphin and Okular in the foregroud, Telegram Desktop in the
background.
I clicked the "Show Desktop" button, then started adding the Memory Status
widget.
I was curious if Ctrl+Z would revert the creation of the widget, but instead
Plasma crashed.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
